I keep thinking a bigger frame might be a way to go, but that is a lot of work and a bundle of cash. I saw in one mag a custom bike built for a tall guy, he looked proportional when it was completed. But that was a high dollar build.
At my first look, I didnt see any Santee frames that said anything about being right for someone tall. Someone must make one.
Cutting up your frame and stretching it would require a frame jig, and that could run up the costs too.
Have you tried any of the forward controls and taller bars yet?
At Street vibes last weekend I laughed when my 5'2" wife walked past a bike and had to look 'up' at the handlebars of a bike. I stood there and tried to figure out how tall the guy would hafta be to ride that thing. I am at 6' 0" and I dont think I could have rode it.....
